Detailed description of the invention
Below in conjunction with the utility model is further explained the explanation of specific embodiment and Figure of description.
Referring to Fig. 1 and Fig. 2, the reverse speed shift rod of variator main tank, one or two grades of shift fork axles, three shift fork shaft No 4s and five or six grades of shift fork axles are arranged on differing heights, the reverse speed shift rod of variator main tank, one or two grades of shift fork axles and three shift fork shaft No 4s are respectively arranged with 1,1 grades of guide blocks of reverse gear guide block 2 and three fourth gear guide blocks 3, five or six grades of shift fork axles are provided with five or six grades of shift forks 9,1,1 grades of guide blocks of reverse gear guide block 2 and three fourth gear guide blocks 3 are provided with equivalently-sized allocating slot; Speed-changer operation device is provided with gear shift shifting block 4, gear shift shifting block 4 is provided with shifting block and allocating slot, 1,1 grades of guide blocks of shifting block correspondence reverse gear guide block 2 of gear shift shifting block 4 and the allocating slot of three fourth gear guide blocks 3, cab bar can drive gear shift shifting block 4 translation and rotation; Five or six grades of shift fork axles are provided with swing shifting block 7, swing shifting block 7 one end and be fastened on five or six grades of shift forks 9, the other end is provided with the shifting block corresponding with the allocating slot of gear shift shifting block 4, and the shifting block swinging shifting block 7 adopts spherical shifting block, and gear shift shifting block 4 can drive swing shifting block 7 to rotate.
Swing shifting block 7 passes through commutation support column 5 and is arranged on the housing 6 of variator main tank, and the centre position swinging shifting block 7 offers through hole, and swing shifting block 7 is set in by through hole and commutates on support column 5, and swing shifting block 7 can rotate around the support column 5 that commutates. Commutation support column 5 is positioned at the lower section of speed-changer operation device, and is in same perpendicular with horizontal shift bar center.
Five or six grades of shift forks 9 are installed with shift fork commutation post 8, shift fork commutation post 8 and five or six grades of shift forks 9 in integral type or split type setting, swing shifting block 7 one end and offer slotted eye, swing shifting block 7 and be fastened on shift fork commutation post 8 by described slotted eye. When variator is in neutral position, the shifting block of gear shift shifting block 4 is positioned at the allocating slot of three fourth gear guide blocks 3.
Referring to Fig. 1 and Fig. 2, 4 shift fork axles of variator main tank are not at sustained height, reverse gear guide block 1, one or two grades of guide blocks 2, three fourth gear guide blocks 3 all have the allocating slot of same widths, gear shift shifting block 4 is provided with a shifting block and an allocating slot, the shifting block correspondence reverse gear guide block 1 of gear shift shifting block 4, one or two grades of guide blocks 2, the allocating slot of three fourth gear guide blocks 3, the allocating slot correspondence of gear shift shifting block 4 swings the shifting block of shifting block 7, Fig. 1 and Fig. 2 is that variator is in neutral position, the shifting block of gear shift shifting block 4 is exactly in the allocating slot of three fourth gear guide blocks 3, the allocating slot of gear shift shifting block 4 has certain gap with swinging shifting block 7, swing one end correspondence gear shift shifting block 4 of shifting block 7, the other end blocks on the shift fork commutation post 8 being arranged on five or six grades of shift forks 9, shift fork commutation post 8 and five or six grades of shift forks 9 can be made of one when not affecting assembling. swinging the central aperture of shifting block 7, swing shifting block 7 is arranged on housing 6 by commutation support column 5 by this hole, makes swing shifting block 7 can rotate with the support column 5 that commutates for fulcrum.
Fig. 1 and Fig. 2 is the situation that variator is in neutral position, the shifting block of gear shift shifting block 4 is in the allocating slot of three fourth gear guide blocks 3, when driver is directly pushed forward into gear by the stick of driver's cabin, gear shift shifting block 4 is around its axis back rotation, drive three fourth gear guide blocks 3 together with three shift fork shaft No 4s and three fourth gear shift forks along the axis rearward movement of three shift fork shaft No 4s, be linked into three fourth gear; When selecting one or two grades or reverse gear as driver, gear shift shifting block 4 is along its axis translation, and shifting block enters in the allocating slot of one or two grades of guide blocks 2 or reverse gear guide block 1, hangs shelves implementation identical with three fourth gear.
When driver selects five or six grades, gear shift shifting block 4 moves along its axis to five or six grades of shift fork directions, makes allocating slot snap in the spherical shifting block swinging shifting block 7, and the shifting block of gear shift shifting block 4 departs from the allocating slot of three fourth gear guide blocks 3 simultaneously. If now driver is linked into forward gear, now gear shift shifting block 4 rotates about the axis thereof, its allocating slot rearward rotates, drive and swing shifting block 7 with the support column 5 that commutates for fulcrum (axle center) rotation, the other end swinging shifting block 7 drives five or six grades of shift forks 9 to move forward, consequently, it is possible to the gear shift direction of gear shift shifting block 4 is backward, the direction of motion of five or six grades of shift fork axles is forward, namely achieves extension shelves commutation; In like manner, if driver is linked into gear backward, now gear shift shifting block 4 rotates about the axis thereof, and its allocating slot forwards rotates, driving and swing shifting block 7 with the support column 5 that commutates for fulcrum (axle center) rotation, the other end swinging shifting block 7 drives five or six grades of shift forks 9 to move backwards.
Current normally used overgear mechanical reversing mechanism is to be arranged on different shift fork axles by shift fork and the guide block of overgear, the center requiring involved shift fork axle is in same level, and the swing shifting block, guide block and the strong point that commutate used are generally all in the front end of manipulation device. And the partition wall of manipulation device distance one axle head of S12 is close, it is impossible to arrange conventional changement, at manipulation device rear also without enough spaces. Meanwhile, 3 shift fork axles of five or six grades of shift fork axles and all the other gears are not at sustained height, and spacing is also different. For the problem overcoming existing changement to use, this utility model devises a kind of new reversing arrangement, the fulcrum swinging shifting block is positioned at the lower section of manipulation device and is in same perpendicular with horizontal shift bar center, swing shifting block to be directly connected with gear shift shifting block and five or six grades of shift forks, without using other shift fork axle, and it is highly different according to actual needs to swing shifting block two ends, by this scheme, solves the problem that existing changement cannot be arranged.
